ECS-3951M-018-BN-TR Oscillators

Oscillators are important components in many electronic circuits, which are used to generate waveforms of constant frequency and shape. The ECS-3951M-018-BN-TR is a surface mount, low cost, low power series of oscillators manufactured by Ecliptek Corporation.The ECS-3951M-018-BN-TR oscillator features a small form factor of 3.2mm x 2.5mm and an operating temperature range from -30°C to +85°C. This device is available in two standard frequencies, 16.000MHz and 18.000MHz. The low jitter performance ensures that the signal generated is almost perfectly clock signal, making it perfect for demanding timing applications.The ECS-3951M-018-BN-TR oscillator is a highly stable, low noise device. It operates at a temperature range of -30°C to +85°C and comes with an integrated load capacitance. It has an output type of TTL/CMOS and features low current consumption of 0.6mA at 20MHz and 0.9mA at 25MHz. The device is also RoHS compliant.The ECS-3951M-018-BN-TR oscillator can be used in an array of applications such as clock synchronization for microprocessors, clock reference for cellular systems, and controllers for automotive systems. It is also ideal for sensor modules, Bluetooth applications, and timekeeping applications.Working PrincipleThe ECS-3951M-018-BN-TR oscillator works on the principle of relaxing oscillations. Oscillators, in general, are composed of two main components, an oscillating element and an amplifier. The oscillating element is the section responsible for generating the signal itself, while the amplifier serves to maintain the signal and prevent it from decaying.The oscillating element of the ECS-3951M-018-BN-TR consists of two positive feedback pathways, an RC oscillator and a crystal resonator. The RC oscillator is a low pass filter made of a resistor and capacitor, and serves to convert the DC input into an AC signal. The crystal resonator acts as a bandpass filter, filtering out any frequencies outside its specified range.The amplifier is composed of two transistors, one in each feedback pathway of the oscillator. The transistors act as switches, alternating between their two states. This produces the oscillating output. The amplifier also dampens the output so that it does not become excessively loud. The combination of these two elements forms a low power, high frequency oscillating signal.ConclusionThe ECS-3951M-018-BN-TR oscillator is a low power, low cost, surface mount oscillator suitable for various timing application. This device is RoHS compliant and offers two standard frequencies. It works on the principle of relaxing oscillations, composed of an oscillating element made of two positive feedback pathways and an amplifier. This ensures stable, repetitive signals that can be used in a variety of applications.
